Birth control pills

If the Androgenic Alopecia does trigger than you have to give up taking the pill. After this you will experience up to six months of hair loss stopping eventually. In some cases the hair does not grow back in the places where it fell.

IVF treatments

Some women report hair loss because of the swings in hormones caused by all the injectable and non-injectable drugs involved in IVF procedures.

Others believe that the hair loss is not because of the in vitro fertilization, but because the procedures are very stressful for some women.

Hormones

Hormones can influence the hair loss of both men and women. For women the hair loss translates through thinning of the hair while in men baldness appears from the front to the crown of the head. One factor that can influence your hair loss is DHT or Dihydrotestosterone which can be found in all bodies.
